f ,'Myinvention relates to plumbl Wires .used

in elevator shafts for the plumbing of the lateral guide rails while a building is under' vide a protective housing 'or the plumbvvire, whereby the latter may be 'immune to air currents or. Wind pressure Within the structure of the building. Y l p In modern building'constru'ction, work on the elevators proceedsfbefore [the building lWalls or partitions arebui'lt up, and vair currents and wind have to be contended With becauseo the'open condition of the building.

den'otes-tlie .sections of 'the rail, thesebeing Iinvertical superposed succession. The vrail' is generally conslderedas continuous andthe onlyfincidents therein are the` joints of the l sections and attaching brackets at each floor fofthe buildingytheflatter not beingshown.

In plumbing n a given rail, what .is usually designated as, ya J ohnson`clip-r12 is attached f to the-Web ll' of the rail at the Vtop thereof, theeplumb Wire ldepending 'from the clip in front of .the Webl as vindicated infFigure 2f The sectionsfoffthe rail are thenl adjusted nd alinement "with l they plumb Wire. f

The novelhousing is gnerally inthe form :0f @Square tube composed of a verticalseries tof. sectionsJA; arranged oppositethe rail Web ll. One.vvall 'of the'sections is divided as shown tol 'receive the Orepart-,of-- the web.L i

Within it, and the divisions lla are oisetto# Ward each other at 14h to conform to shoul- :ders 149 O11 tliesides of the Web thelatteiY VVbeing reduced in lthickness between these* shoulders and the base.

K Theldivisions eXf tendv along thereduced portion off.the.,\vebto a short distanceromthey base of therail Where 'theyterminate'fiaredly as indicated at f 14rd. The housing sections may thus be considered as having clip extensions engageable with the web 11 as indicated in Figure 2 for purposes of attachment and support.

In order that the housing sections may be laid out and applied with facility to a given vrail, it is preferable that they be arranged spacedly in their sequence. However, Vin order that the spaces between the sections may not form a passage for air currents with detrimentalk effects upon the plumb .wire 13 l see fitto cover the ends of the sections contiguous to each space witlia band 15 similar in shape to the housing sections, but much shorter in length. The housing is now a coinplete enclosure for the plumb wire, yet'takes housing or bands are drawnopen. No. fastening devices are Vrequired to maintain the engagement of the housing vwith the web of the rail, but the safety lfeature is providedin case one loosens or removes a housing section and accidentally permits it to drop, as

such ahousing section may be at a high; point in the building, andit may drop a long distance and endanger the safety of persons or objects at lower points in the elevator shaft.A

The safety device referred to consists of a chain 16 secured at one side of each section to an eye or other permanent fastening device 1'? and caught on the other side of the housing in a snapper 18, hung from an eye 19 secured to such side of the section. Thev chain is permitted te extend with a number of links beyond the snapper, so that it may be adjusted with .reference to the latter. When a given section is applied as heretofore de'- scribed, the chain is wrapped around the rail 10 as clearly shown in Figure 2 and caught in the snapper, this operation anchoring thev section to the rail. In case a joint of rail sections ora bracket connectionwith the rail occurs opposite the site of the chain, thelatter is of suliicient length to be raisedY or lowered,ftol avoid the enlargement, due to the eXtra links terminally provided as explained.

In the use'of the novel housing, one or` more sections are removed at each point' where the rail is tested for plumbing'purposes. Thus,'if any air disturbance exists in the shaft, it will have practically no eiect upon the steadiness of the plumb wire 13, as only a few feet-of the wire will be exposed.

My calculation is to construct the 'housingsections in four-foot lengths or thereabouts,l the removal of one section at one point or another being both sufficient for attention to the plumbing requirement and safe as against ordinary air conditions. However, should plumbing be required on a windy day, some extra sections may be had which are in short lengths, such as one-foot or thereabouts, and the sections so arranged that but a limit-ed space is open in the housing at the particular point where thetestingV and adjusting is done,"`leaving practically the entire course 'of the plumbing wire fully. enclosed and protected against the swaying influences of the wind.

1n applying any section to the web 11 of the rail it is evident that but direct pressure is required-to thesame since the flared ends 14d permit the easy progress of theclip entensicn' over the web 111,Y Howeven for facility in removing any section, I have devised the tool of Figure'll. ThisV tool'is in the nat-ure of a fork 2O with a rearwardly eX- tending liandle 21.. Oneprong of the 'fork carries a block 22 whilethe other'calries a similar block 23. rlhe block 22 is fast on its prong, while the block 23 is carried by a stem 24 which passes'through an o'ifsetu25 of the corresponding prong 2O in an'outwarld direction to receive a fingerfknob 2G." lhenthe stein 24 has been drawn outwardly to seat the block'28 inthe odset 2.5, the spacing of the blocks 22 and; 23 is SliCll as to straddle the housing section when the fork is advanced upon the same. However, kwhen the prongs have reached Va position opposite the clip portion ofthe housing, the block 28 may be advanced to close in toward the ,correspendingside of the'said'clipA section and thus secure a retaining ,relation `toward the housingf N ow,A by depressing the `handlev21, the see; tion maybe wrenched vloo'se from the railA Web'll, eliminating what diiculty may be involved in that respect Vif they removalY were done byhand. K

It will be seen that .thehousing primarily a thing' of eXtreme compactness',since'it eX- tends only to the immediate surroundings ofv the plumb wire. ln effect, the housing has;

a high protective efficiency, enabling the plumbing of the guide rails to be done at any time ,and without vspecial attention to atmospheric conditions. At the same timefthe housing isffiexible of application andin use by-reasonof its sectional construction and:

freedom: from accurate adjust-ment. In'other words, the sections .of the housing may beA applied'roughlyV and without the use of any' skill, .since the overlappingbands.cover it completely irrespective ofthe spacing of the sections'.` The a aplianc'e requiresV no fastening device orY la or in tliatfconnection, and is entirely `safe by virtue of the chain anchor.- ing `expedient described, lA suitable lid may be applied at the top or" the housinglto'keep out rain, dust, etc; Further, the plumbing wire is protected against impact and `kirrling influences ofobgects and persons coming in contact with the same; thus, once'the rail .hasrbeen hung and the housing applied, the Wire hangs freely and finds its position naturally. Needless to say, the housing on ack count'of its simple and sectional form can be removed from the rails in one building and taken along to the next job in anotherV about the wire, and open in one of its sides to receive the rail web, and bends from thesections of the open side extended upon the sides of the web to engage the latter.
